14.4.3 Transform

A rotational transformation can also be applied to the texture image prior to texture mapping. This is a fairly unusual operation but might prove useful for specialized operations or to implement special effects. The TextureTransformTest example creates a texture mapped Box and allows the user to interactively rotate the texture applied to the Box using the mouse (figure 14.24).

Figure 14.24 Applying a Transform to an applied texture image. TextureTransformTest allows a texture image to be interactively rotated using a MouseRotate behavior. The ColorCube at the lower left of the two frames shows the current rotation


Note that only the rotational components of the Transform3D appear to be used.
